Researchers at Trinity College Dublin have made significant strides in understanding the evolution of human oral health by analyzing ancient dental remains. Genetic secrets uncovered from 4,000-year-old teeth found in an Irish limestone cave have illuminated the impact of changing human diets over the centuries. Scientists successfully recovered preserved microbiomes from two teeth, revealing major changes in the oral microenvironment from the Bronze Age to today. The genetic analyses of these microbiomes found evidence of bacteria that cause tooth decay and gum disease, offering insights into the deep diversity and recent adaptive episodes for human oral pathobionts, as reported in Molecular Biology and Evolution. This breakthrough comes after archaeologists faced challenges in acquiring full genomes from oral bacteria for years, marking a significant advancement in the field.

Archaeologists have faced challenges in acquiring full genomes from oral bacteria for years, but two ancient teeth found in Ireland have now helped fill in the history of oral health. https://t.co/wEHEQKgk2o
I’m about to try lumina, the toothpaste that you use once to bring genetically engineered bacteria into your mouth. These bacteria outcompete the bacteria that cause cavities, meaning no more tooth decay! The future is wild. Thanks to my good friend @Aella_Girl. https://t.co/G344wBsyxk
